MECHANIGALLY-OPERATED ADVERTISING DEVICE.

Application filed. February 4, 1921.

To all whom it may concern Be it known that I, ARCHER As'roN of 25 Cliff road, Hyde Park, Leeds, in the county of York England, a British sub3ect, .have invented certain new and useful Improvements in or Relating to Mechanically- Operated Advertising Devices, of wh1ch the following is a specification.

This invention relates to a mechanically operated advertising device and has for its primary object means for demonstrating the action of what is known as a lever-type self-filling fountain-pen. For the sake of convenience the invention will be described solely with reference to such a pen but it is to be understood that the invention may also be employed for other purposes for which the mechanical movements are sultable.

Apparatus constructed in accordance with the present invention comprises a model of a pen or other article having a lever or similar element adapted to be given a swlnging movement of the kind set forth, means for raising and lowering the model and means for angularly displacing the lever thereof at predetermined points in the path of said model- One form of the invention is illustrated in the accompanying drawings wherein Figure 1 is a front view of the apparatus, Fig. 2 is a sectional side elevation thereof on an enlarged scale, Fig. 8 is a sectional front elevation on the line 3-3, Fig. 2, parts being omitted and others partly broken away, and Fig. 4: is a View similar to Fig. 3 but showing the parts in different positions.

As shown in Fig. 1 a model a of a levertype self-filling fountain pen is mounted upon a disk 72 which serves to cover an opening in the front wall 0 of a casing for the apparatus, said opening being indicated by dotted lines at c, and a bottle cl of fountain pen ink or a like receptacle is placed vertically below the model a for which purpose the front wall 0 may be gapped as at c. As shown in Figs. 2, 3 and 4 the model a, instead of being mounted upon the disk 6, is in reality carried by arms f, 7 projecting forwardly through opening 0 from cross bars 9, h the ends of which are slidable on upright guide bars j, j and the disk 7) is in fact mounted on the model a. Clamped to the guide bars 7', 7' by set screws 79, la and lock nuts m, m is a cross bar 71. provided cen- Specification of Letters Patent. Patented J n 14 1921 Serial No. 442,468.

traily with a bearing for the spindle 0 of a worm wheel 3) with which meshes a worm g on the spindle r of a pulley 8 adapted to be driven by any suitable prime mover such as clockwork mechanism, an electric motor or the like, not shown.

On the front end of the spindle 0 is eccentrically mounted a substantially heartshaped cam t on the peripheral surface of which rests an anti-friction roller 14 rotatably mounted on the cross bar g, the construction being such that when the pulley s is driven the cam t isrotated and causes the cross bar 9, and consequently the model a, disk I) and cross bar it, to be raised and lowered alternately. As shown in'Figs. 3 and 4: the cam t is symmetrical and adjacent each end of its axis of symmetry its peripheral surface is arcuate about its center of rotation so that the model a pauses at the top and bottom of its travel.

Mounted on the arms 7', f is a plate 1) Fig. 1), which serves to carry pivot pins and as an anchorage for springs as hereinafter set forth. The lever so of the model a is rigidly connected by a bar to with one arm got a lever y, .2 which is pivoted on a pivot pin 11 mounted on the plate '0 c'oaxially with the pivot of the lever to the other arm 2 of the lever 3 z having secured thereto one end of a tension spring 12 the other end of which is anchored by a screw 13 to the plate 0), the bar a passing through an arcuate slot 14 in the disk I) and plate o and the spring 12 tending normally to hold the lever w in its closed position as shown in Fig. 2. On the face of the cam 16 and substantially on the greater radius of its axis of symmetry is mounted a lug 15 carrying a tripping piece in the form of an antifriction, roller 16 adapted to engage a curved faceon the arm {1 of the lever y, a so as, during the revolution of said cam, to rock the lever y, 2 about its pivot 11 through an angle of about 90 after which the eccentricity of the cam and the lowering of the plate 7) and consequently the lever y, .2

causes the antifr-iction roller 16 to disengage from said arm. Before such disengagement takes place, however, the bar a: is engaged by the hooked end 17 of a detent lever 17, 18 pivoted on a pivot pin 19 carried by the plate '2), the arm 18 of said lever being acted upon by a tension spring 20 one end of which is attached to said arm 18 while its other end is anchored to a screw 21 on the plate v. The arm 18 of the lever 17, 18 has a pin 22 mounted thereon so as to project into the path of the antifriction roller 16 so that when said pin 22 is engaged by the antifriction roller 16 the lever 17, 18 is rocked about its pivot 19 against the action of its spring 20 so as to disengage its hooked end 17 from the bar wand release the lever y, 2 to the action of its spring 12, thus causing the lever w to be restored to its normal position.

Fig. 3 shows the operative parts in the positions they occupy when the model a is inits lowermost position and after the lever w has been restored to its normal position and Fig. 4E showsthe operative parts in the positions they occupy when the model a is in its highest position and just before the arm y of the lever y, 2 is engaged by the antifriction roller 16, said lever being shown in dot and dash lines in the position it occupies when the bar :0 is engaged by the hooked end 17 of the lever 17, 18. p

In use the model being in its highest position and the operative parts being in the positions shown in Fig. 4 and the prime mover being started the cam t'is revolved about its axiso and the model remains stationary, the antifriction roller 16 engages the arm 3/ of the lever y, 2 and rocks the latter through substantially 90 until the bar x is engaged by the hooked end 17 of the lever 17, 18 the lever w being thus rocked through substantially 90, to deflate the rubber bag in the model a and held in said position. Continued rotation of the cam t permits the cross bar g,'and consequently the modela, to be lowered the antifriction roller u resting on the periphery of said cam, until the model a dips into the receptacle d. The engagement'of the antifriction roller 16 with the pin 22 on the arm 18 of the lever 17, 18 disengages the hooked end 17 'of the latter from the bar a: and permits the lever to to be restored to its normal position as above set forth the model a thus sucking up ink from the receptacle (Z. During this action the antifriction roller u is resting ona portion of the periphery.

of the cam 73 which is of constant radius so that the model a remains stationary. Continued rotation of the cam t raises the cross bar. '9 and consequently the modela until the latter .is at its highest position in which it again remains stationary. The subsequent engagement of the antifriction roller 16 with the arm y of the lever y, e deflates the bag of the model and expels the inlc therefrom and so on.

In this manner the ease and simplicity with which a pen of the kind mentioned may be refilled is efiiciently demonstrated. 1 claim 1.
